Editor crashes when inserting a map item

What I did:

Start editor
Create map
Click on “Map items” and press [Insert]

The editor crashes with this error:

cdogs-sdl-editor: /home/wuzzy/src/cdogs-sdl/cdogs-sdl/src/cdogs/c_array.c:101: CArrayGet: Assertion `idx >= 0 && idx < (int)a->size' failed.

This may be related to #308, but the backtrace looks different, so I filed a new issue.
